It features a very wide voltage input range from 10 to 50 volts. This allows the unit to operate with 12, 24, or 48 volt battery or distributed DC power systems. This high-efficiency power supply design supports ATX-compatible signals so it can use power management modes. ATX mode support Power On/Off, Power Good, and +5VSB to allow software controlled shutdown and sleep modes. Each output is short circuit protected and current limited. A minimum load is not needed to bring the supply into regulation. When power is applied to the board, five LEDs will illuminate providing a visual status that power is available for the +5V, +3.3V, ±12V, and +5V standby. If one of these LEDs is not lit or is pulsing ON and OFF, then the respective supply voltage is not in regulation. A pulsating LED is an indication that the respective converter is in current limit. There is also a connector for an ON/OFF switch for remote PPM-DC-ATX-P Block Diagram shutdown of the system. However, the +5VSB source will WinSystems | 715 Stadium Drive, Arlington, TX 76011 USA | Tel 817-274-7553 | [email protected] | www.WinSystems.co

The board is populated with low-profile, soldered down, surface mount components which keep the overall height of the board low. The PPM-DC-ATX-P is designed to operate at extended temperatures without forced air cooling or heatsink. This maximizes reliability and reduces weight for the module and the system it powers. Input Connector - A Phoenix Combicon connector allows for power to be easily and securely brought to the board with a quick way to remove it if necessary. The mating connector is shipped with each standard board. PC/104-P/us Connectors - The ground, power and control signals are...
